I used PHD2 drift align, it looked good. But I am not sure because each sub had ~0.01-0.02 degree field rotation, which I did not expect with good PA. I usually see big field rotation if PA is bad,

The new Keypad Version coming out will let you use the keypad to build a model.

I’m looking to see if anyone has built a pointing model with a CP4 by a sequence of GoTo, platesolve, sync (refine) through Stellarmate. It's great that we have APCC Pro (which I'll receive with

Hi Yanzhe, Can you zip and post your PHD2 logs, as well as APCC/AP V2 ASCOM driver logs? There might be something useful there. -Ray

Do you have a picture of your guide chart? The Dec axis would not creep under gravity if the clutches are tight. I just checked a mount with 3 lb out of balance in Dec and see zero creep or any other

Roland, I will check my mount serial number later as I just packed everything due to rain forecast. My camera's orientation was 0/180 degree, so I assume top to bottom elongation would be DEC. I dont

In a previous post discussing encoders for our various mounts I posted this: "The main difference is that the ring diameter of the 1100/1600 mounts is 100mm, the Mach2 uses a 75mm ring." It should

My setup is FSQ106+OAG+16803. The same setup has been used for a while with a different mount, so it is unlikely the collimation or fan issue. Yanzhe

Couple of questions: 1 - what's the mount's serial number 2 - which axis is the elongation 3 - which direction was the scope pointing (RA-Dec) 4 - what scope and focal length or what is the arc sec

Take a short exposure (1 sec or less) of a bright star inside, outside and at focus. I was shooting the other day when the temperature was dropping rapidly after sunset and got heat plumes for about 1

If your guiding was spot on, then the mount is working correctly. It is not a balance or setup issue. Balance would not cause oval stars. The mount would be suspect if one axis had rms guide values

Can you describe your imaging setup? (Telescope, camera, image scale, etc.) Is it possible the issue is optical (collimation) or caused by vibrations from the camera's fan? -Ray

I’ve only had the mount six days, but I’ve been able to use it every night, so that’s kind of the equivalent of maybe three months of experience under normal conditions around here. Looks like

Yep that looks like the right one!

Lucky guy. I have been under cloud cover since late November with no signs of improvement anytime soon....

My Mach2 brought 2 months of clouds (well it finally let up up last night, and tonight promises to be good as well). I guess I’m happy for you.....kinda...sorta... OK actually I’m bitter with a

Good question. My guess is that it would stall.

For the 1100GTO, I have this simple ADM bracket to work perfectly......

This got my curious since I ordered from OPT the PoleMaster Adapter for my soon coming 1100GTO(same adapter I believe). It arrived a couple months ago and I never bothered to open it, so I just did

I got the exact same one, returned it and waiting for the new one.
